RE: Wheel paint question
I would advise clearcoating them as well. As long as they're properly cleaned and prepped, you shouldn't have problems with flaking or peeling.
Wet-sanding wheels can be tricky, since with all the cracks and crevices, it's easy to accidentally sand down through the paint to the primer or the underlying metal. As long as you're happy with the quality of the silver finish, you can just wet-sand the easy-to-reach places and then clearcoat the whole wheel.
Also, if you're mixing the clearcoat yourself and applying it with a spray gun, use a "faster" reducer than you would normally use for the ambient temperature. Parts with a lot of nooks and crannies are more prone to drips, runs and sags, and a faster reducer will help the paint set up more quickly.
